fender flares for 75 cj5

There appears to be a large number of fender flares available for older cj 5's. Many are advertised as up to 6 in of coverage with very little info available. I am looking for the flexible type for a 1975 cj5 has anyone had good / bad experiences with certain manufacturers?

 

I just bought some cheapies from 4 Wheel Parts. They went on easy and are holding up pretty good considering the abuse they get.
